AI-Powered Email Subscription Service with Forms, Airtable & Gmail

This n8n workflow creates a complete email subscription service for newsletters or regular content delivery. Users subscribe via a customizable n8n form, providing their email, topic interest, and delivery interval (e.g., daily, weekly). Submissions are automatically stored in Airtable as a database of subscribers.

A daily scheduled trigger scans Airtable for due subscribers based on their intervals. Matching users trigger a subworkflow that leverages an AI agent (OpenAI-compatible) to generate tailored text content and a vision model to create accompanying images. The content is then bundled into a personalized email sent via Gmail, including a unique unsubscribe link for easy opt-out.

The unsubscribe process mirrors subscriptions: a form submission updates the Airtable record to disable future sends. Benefits include zero-coding setup for scalable marketing automation, time savings on content creation, and high engagement through AI-personalization. Ideal for company newsletters, promotions, educational series, or social media content distribution.

Customization is straightforward—extend to other channels like WhatsApp or Telegram, swap AI providers, or adapt for e-commerce upsells. Requires Airtable base (sample provided), OpenAI API, and Gmail credentials. Perfect for marketers, creators, and businesses seeking efficient, hands-off subscriber management.
